A Literal “New Spin” on Hybrid Milling/Grinding Machines

Mitsui Seiki’s Vertex hybrid machine borrows a jig grinder’s motion to complement high precision five-axis milling.

“The concept is to emulate jig grinding equipment,” says Robb Hudson, CEO of Mitsui Seiki USA, when describing a new family of Vertex five-axis hybrid vertical machining/grinding centers in booth 338519. Hudson explains that this concept is literally a “new spin” on milling/grinding hybrids, because the machines can apply a part spinning process that produces tangential planetary work spindle alignment, much like the U-axis motion of jig grinding equipment. Combine this with high speed 3+2 or full five-axis milling that is capable of 0.0003-inch (5.5 µm) precision, and the result is a machine that can carry out critical applications such as lights-out machining of die/mold, optical and tooling components, Hudson says.

The Vertex Hybrid G 55-5X machine on display has two larger siblings in the family, the 75-5X and the 100-5X. The show machine is demonstrating its capabilities with a combination of milling and grinding operations on a D2 steel plate, hardened and heat-treated to 60 to 62 HRC. A form milling tool is roughing and pre-finishing corner relief, followed by a form-grinding wheel for finishing. After a rounded triangular pocket is milled in the part’s center, a variety of grinding wheels form critical step features.

“We are claiming it has CMM-level precision because the engineered accuracy and rigidity meet volumetric calibration according to ISO10320-2 using the latest FANUC 3D volumetric compensation features, while enabling us to apply in-process 3D measuring capability traceable to the National Institute of Standards and Technology,” Hudson says. He adds that the machine’s structure, which features hand-scraped guideways, is configured to attain positioning accuracy in the X, Y, and Z-axes of 0.000040 inch (0.001 mm), ±6 arc seconds in the A axis, and ±4 arc seconds in the C axis.

“But the grinding aspect of this machine is the cool part,” Hudson says. “It’s not tacked-on. We have automatic, in-process grinding wheel dressing, size measurement and wheel calibration, plus an advanced thermal compensation system to enssure size consistency”

Hudson invites attendees to check out the machine for themselves. “They can see that this is not just a spin we put on the story.”

World’s First Carbon Fiber Monocoque Smartphone Introduced

Carbon Mobile, maker of the new Carbon 1 MK II smartphone, is moving the industry forward with a thinner, lighter, and more sustainable device.

According to the company, the electronics industry creates 50m tons of e-waste every year and 80% is not recycled. The materials used in the Carbon 1 MK II not only reduce weight and strengthen the device, but they can also be more easily broken down and reused for future devices.

The shape of the Carbon 1 MK II is a monocoque design and it is made of hybrid carbon fiber composites. Due to the strength of the design and the material, there is no need for a metal internal frame, further lightweighting the device. The use of carbon fiber brings the weight of the device down to 125 g, 33% less than the average smartphone weight of 182 g. The phone is also 25% thinner than the average 8.3 mm thick smartphone at only 6.3 mm thick. The reduced weight and size make the device easy to carry and use. Not only is the phone light and strong, it’s also sleek featuring a carbon fiber matte black color.

In the past, smartphone designers turned away from carbon fiber as a design material because of its signal blocking properties. After four years of research, Carbon Mobile came up with its patent-pending HyRECM® Technology (Hybrid Radio Enabled Composite Material Technology) forging carbon fibers with complementary ‘radio-enabled’ composites.

Explaining the direction of Carbon Mobile, CEO and chief technology officer Firas Khalifeh said, “We created Carbon to explore where others won’t dare and bring you the beautifully crafted miniature and sustainable tech of tomorrow, quicker. Through relentless R&D, we challenge the conventions of an industry that repeatedly ignores its responsibility to the planet and its people in the resources and processes it relies on.”

Looking into getting an audible buzzer system for the shop floor to signal shift start, break, end, ect…. I’m looking around online and the median price is $500+ ! It’s an alarm clock with a buzzer, why is it so expensive?

Anyone here have a good low-cost brand to offer up?
